AI agents call binance_calculate_funding_cost to retrieve information from Binance without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool calculates and estimates funding costs based on position parameters and real-time funding rates. It is a read/analytical tool that queries market data and performs calculations. It does not place orders, move money, or modify any state. Despite being on a financial trading server, this specific tool only reads data and computes estimates.
From the tool's definition 计算USDT永续合约的预计资金费用成本 - this is a calculation/estimation tool that retrieves market data (funding rates) and computes projected costs without executing any trades or modifying state
Documented attack patterns abuse exactly the kind of access binance_calculate_funding_cost gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Binance, and nothing reaches the server without passing your rules. This is the rule we recommend for binance_calculate_funding_cost:
{
"version": "1",
"default": "deny",
"tools": {
"binance_calculate_funding_cost": {}
}
}binance_calculate_funding_cost is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
